Glycerol could be an interesting polyol &lt;span class=&quot;hitHilite&quot;&gt;for&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;acetalization&lt;/span&gt; with &lt;span class=&quot;hitHilite&quot;&gt;furfural&lt;/span&gt; due to its low cost, and it is produced as a byproduct in very large amount in the process &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; biodiesel production. In this work, glycerol &lt;span class=&quot;hitHilite&quot;&gt;acetalization&lt;/span&gt; with &lt;span class=&quot;hitHilite&quot;&gt;furfural&lt;/span&gt; has been selected as a model reaction. &lt;span class=&quot;hitHilite&quot;&gt;Acetalization&lt;/span&gt; reaction was performed under neat conditions (solventless) with 1:1 molar ratio &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;furfural&lt;/span&gt; and glycerol at room temperature over various acid catalysts, including homogeneous and heterogeneous acids. Among several catalysts, Zr-Mont, a heterogeneous solid acid having controlled acidity, gave as high as 78% isolated yield &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; acetal products. Interestingly, acetal products can be isolated in pure form by performing extraction using cyclohexane that enables selective extraction &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; product, and unreacted glycerol and &lt;span class=&quot;hitHilite&quot;&gt;furfural&lt;/span&gt; were left in aqueous phase, which can be recycled. Further, to make &lt;span class=&quot;hitHilite&quot;&gt;fuel&lt;/span&gt; components &lt;span class=&quot;hitHilite&quot;&gt;from&lt;/span&gt; isolated acetal product &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; glycerol and &lt;span class=&quot;hitHilite&quot;&gt;furfural&lt;/span&gt;, &lt;span class=&quot;hitHilite&quot;&gt;hydrogenation&lt;/span&gt; was performed over a series &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; supported noble-metal catalysts under low H-2 pressure at room temperature. Among them, 5% Pd/C showed very high activity &lt;span class=&quot;hitHilite&quot;&gt;for&lt;/span&gt; ring &lt;span class=&quot;hitHilite&quot;&gt;hydrogenation&lt;/span&gt; that resulted in high yield &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; &lt;span class=&quot;hitHilite&quot;&gt;hydrogenation&lt;/span&gt; products. However, hydrogenated product contains free hydroxyl group that needs to be subsequently etherified or acetylated. Interestingly, etherified derivative was obtained in high yield compared to acetylated derivative. In addition, several other &lt;span class=&quot;hitHilite&quot;&gt;diols&lt;/span&gt; were treated with &lt;span class=&quot;hitHilite&quot;&gt;furfural&lt;/span&gt; and their products were subsequently hydrogenated over 5% Pd/C under very low H-2 pressure. The properties &lt;span class=&quot;hitHilite&quot;&gt;of&lt;/span&gt; resulting compounds were investigated so as to find most suitable candidates as &lt;span class=&quot;hitHilite&quot;&gt;additives&lt;/span&gt; to commercial &lt;span class=&quot;hitHilite&quot;&gt;diesel&lt;/span&gt;.&lt;/p&gt;

	This investigation includes the synthesis and characterization of a new series of ionic liquids (ILs) based on the tetraalkylammonium dication for the absorption of CO2, a step towards the development of more efficient and sustainable technologies. It was possible to synthesize amine-substituted PEG diacrylate by modifying poly(ethylene glycol) (PEG), which was then quaternized with 1-bromopentane to produce the IL PDBr. The other IL products, PDNTf2, PDBF4 and PDPF6, were synthesized via the metathesis of PDBr with the appropriate salt. The synthesized products were characterized using various techniques, such as FTIR, H-1 and C-13 NMR, elemental analysis, and density and viscosity meters, and evaluated as potential sorbents for CO2 capture. DSC and TGA were used to examine the thermal properties of the ILs. As observed from their thermal degradation behavior, the ILs exhibited two-stage disintegration with thermal stability up to 150 &amp;amp; DEG;C. The pressure drop method was used to study the sorption capacity of the ILs towards CO2. The sorption investigation showed that when the pressure is increased, the CO2 absorption increases. Equilibrium is reached in 40 minutes, demonstrating a rapid absorption rate. The IL with the [BF4](-) anion (PDBF4) demonstrated a maximum sorption capacity of 0.577 mole fraction of CO2, and can be regenerated and reused efficiently with less than 0.5% variation from its original absorption capacity. The CO2 absorption capacity for the ILs with other anions follows the trend: Br &amp;amp; AP; NTf2 &amp;lt; PF6 &amp;lt; BF4. This work shows that tetraalkylammonium-based dicationic ILs are adaptable, making them a suitable material for many applications, including sustainable CO2 capture technology.&lt;/p&gt;
